MACHINE FOR STORING WAVE-POWER.

SPECIFICATION forming part of Letters Patent No. 594,078, dated November23, 1897. Application filed February 25, 1897. Serial 110.624.98 1.. (Nomodel.)

To all whom it may concern:

Be it known that we, ALEX P. HAAG, a citizen of Austria-Hungary,andFRANK J. FRIED- RICH, a citizen of Germany, .residing at Fall River, inthe county of Bristol and State of Massachusettshave invented certainnew and useful Improvements in Machines for Storing W'ave-Power; and wedo declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying "drawings, and to the lettersof reference marked thereon,which form a part of this specification."

Our invention relates to machines for storing the power developed by thevertical movement of waves, either of the ocean, lakes, or rivers. Manydevices for this purpose have been proposed, but we believe that ours isnovel, simple, and efficient.

It consists of one or more air-pumps pivotally suspended from a strongframe, an airreceiver communicating with said pump or pumps, and aswinging float connected directly with the piston-rod of each pump andadapted to be swung to and fro and up and down by the waves.

In the drawings, Figure 1 is a side elevation of a portion ofa machineembodying our invention. Fig. 2 is a vertical sectional elevation.

A suitable number of strong columnsA are erected on solid foundations B.We prefer to use metallic columns, as shown, though wooden piles may beemployed, if desired. On a row of such columns, extending out into thewater in a line with the normal direction of the waves, we lay a girder0, preferably an I-beam with wide flanges. Along the top of this girderwe secure an air-receiver D,

preferably a cylindrical tube of cast or sheet of the hanger and ascrew-threaded portion to carry a nut g, which can be tightened againstthe other side of the hanger. The outer ends of the studs arescrew-threaded to receive retaining-nuts The studs project alternatelyto the right and to the left. The columns A also have studs G like thehangers. Levers H are provided at their upper ends with long eyes h,which fit on the studs G and preferably have a lining or bushing h ofBabbitt metal or the like. the levers in place and allow them to swingfreely on the studs. ably bifurcated, as shown, and at their lower endsis secured a float 1, preferably a watertight metallic drum, as shown.Adjacent to each hanger is an air-pump cylinder K, the

on opposite sides of the girders, similarly to the levers H. Thepiston-rods L are connected directly with the levers H, being preferablypivotally attached to transverse bars k between the legs of the levers.

At or near the lower end of the cylinder K is an air-inlet port It. Thepiston M has a port through it, with a downwardly-closing check or flapvalve m. The upper end of the cylinder is provided with a hollowtrunnion N, by means of which it is supported and on which it can swing.The trunnion is journaled in a bearing in a plate P, bolted to thegirder O, and its end is received in a union R, which forms the end of ashort delivery-pipe R, communicating with the receiver or reservoir D. Acheck-valve S retains the air in the reservoir, the pressure being shownby a gage T. At any suitable place on the reservoir there is aconnection d for the attachment of a distributingpipe, by means of whichthe air compressed inthe reservoir can be led off to motors or otherpower-translating devices.

The operation of our machine is as follows: The floats swing up and downas the waves successively pass under them, rocking the levers andreciprocating the piston-rods. The pivotal mounting of thepump-cylinders permits them to swing freely with the movement of thelevers, and the air, compressed by the pistons passes through the hollowThe nuts 9 retain The levers are preferseveral cylinders being arrangedalternately trunnions to the reservoir. By using a large number ofair-pumps it is possible to keep the air-pressure up to a high pointunless the water is perfectly quiet; but even the swell of the ocean,which is always present even on a calm day, is sufficient to keep thepumps at work.

Our invention has but few parts, with no complicated valve motion to getout of order. The rising and falling of the tide does not interfere withthe proper operation of the levers provided the parts are properlyproportioned.

Having thus described our invention, what we claim is-- 1. In a machinefor storing wave-power,tl1e combination with an air-receiver, of one ormore airpumps each mounted on a trunnion, and one or more levers eachcarrying a float and connected directly to the piston-rod of one of saidairepumps, each lever being fulcrumed on a different axis from that ofits pump-trunnion, substantially as described.

2. In a machine for storing wave-power, the combination with anair-receiver, of one or more air-pumps, each mounted on a hollowtrunnion opening into the pump-cylinder and communicating with theair-receiver, a lever connected directly with the pistonrod of eachpump, and a float on the end of said lever, substantially as described.

3. In a machine for storing wave-power,tl1e combination withsupporting-columns, of a girder thereon, a tubular air-receiver mountedon said girder,a plurality of air-pumps, each pump-cylinder having ahollow trunnion journaled in a bearing in said girder, and opening intothe cylinder, a pipe connecting said trunnion with the air-receiver, acheckvalve controlling said pipe, a lever pivotally supported from thegirder adjacent to each cylinder, and connected directly with thepiston-rod of the pump, and a float on the end of the lever,substantially as described.

4.. In a machine for storing wave-power,the combination with'the girderof a series of hangers secured thereto, a horizontal stud at the end ofeach hanger, a lever pivoted on said stud, a float on the end of thelever, an air-pump actuated by the lever, and an airreceiver,substantially as described.

5. In a machine for storing Wave-p0wer,the combination with a girder, ofa series of hangers secured thereto, a horizontal stud on the end ofeach hanger, said studs projecting alternately to right and to left,bifurcated levers each having a long eye pivotally mounted on a stud, anair-tight drum secured to legs of the lever, a transverse bar betweensaid legs, and an air-pump on a trunnion adjacent to each hanger, andhaving its pistonrod connected directly to said bar, substantially asdescribed.

6. In a machine for storing wave-power,the combination with columns A,of girders O,airreservoir D, hangers F secured to said girder andcarrying studs G, bifurcated levers 11 having eyes 71, fitting saidstuds, floats I secured to said levers, cylinders K having airinletports 7c, pistons M having check-valves m, piston-rods L connecteddirectly with the levers II, hollow trunnions N opening into thecylinders and journaled in a plate 1? se cured to the girder, unions Rand pipes R connectin said trunnions with the air-reservoir D, andcheck-valves S controlling said pipes It, substantially as described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
